About Pineocytoma

Pineocytoma is one of several different types of tumors that arise in the area of the pineal gland, requiring different therapies. The exact diagnosis is critical for choosing the correct therapy.

Pineal tumors typically present with hydrocephalus, a buildup of fluid pressure within the brain. A team of experts is needed for optimum therapy. UCLA experts in neurosurgery, neuropathology (microscopic diagnosis), radiation therapy and oncology will work together to provide the best and latest therapies.

If the diagnosis of germinoma is suspected based on the MRI scan as well as the age and sex of the patient (young male), a biopsy may not be required prior to beginning treatment.

Other tests

Some tumors that occur in the pineal region have high levels of certain chemicals (Beta-HCG, AFP, and CEA), which can be detected in the cerebrospinal fluid and/or blood. If detected, a surgical biopsy may not be necessary.

An MRI scan shows a large tumor (arrow) in the pineal region of the brain. The biopsy confirmed glioblastoma, which is rare in this part of the brain. This illustrates the importance of obtaining a tissue biopsy in most cases.

Treatment

Surgical Removal

The surgical removal of pineal region tumors ranks among the most difficult neurosurgical operations. Patients typically are referred to major university medical centers, like UCLA, where certain neurosurgeons have specific expertise in this type of surgery.

Although surgery can be curative in some cases, in other cases it provides a definitive diagnosis and reduces the size of the tumor.
